Because it's amazing. Canada is a very lucky country to have an Organization like RGD, and I think more professionals could use the privilege of have the chance to be part of it. Being a Certified RGD is a way to increase a variety of main directions on my career, besides being recognized.
Most importantly, on how I can participate and give my time and experience to improve different aspects of the area, like mentorship, accessibility and directions of the future of the next generations of Graphic Designers.
The variety of Committees, Events, Awards and structure for its members, is also one of the main reasons, as I can dedicate my efforts to make the whole community stronger and more organized on how RGD can change and enhance the concept of design in the Industry. In the end, RGD provides inspirations and a tangible link to all aspects of the profession.
As a Graphic Design Educator, being an RGD extend that support for my students, and for my own work.

I'm part of the Educator's Committee for a few months and will try to help as much as I can to this area.
